I'm planning to move the Barrack to another place during night time so that in the morning they can start deconstructing their cots right off.
But as I select to deconstruct all Cots, the duplicants will always get up and go back to sleep while they're sleeping.
Please watch the video below.
Would be better to not let Duplicants leave their bed when player try to deconstruct their Cots while they're asleep.
